Staff Statistics Engineer - Feature Flagging and Experimentation

Datadog Datadog · Enterprise · New York, NY · Dev Eng

Datadog is seeking a Staff Statistics Engineer to build new products for Feature Flags and Experiments from scratch. This role involves architecting and implementing a world-class experimentation engine using advanced statistical methods, translating complex statistical concepts into production-ready systems, and influencing product direction. The ideal candidate has deep expertise in statistics and causal inference, with a track record of shipping production-grade software, and is comfortable leveraging AI tools in their workflow.

What you'd actually do

  1. Architect and implement the world-class experimentation engine behind Datadog Experiments, supporting methods like sequential testing, CUPED, variance reduction, and more
  2. Bring rigor to experiment analysis at scale (e.g. through diagnostics, guardrails for safe shipping)
  3. Translate complex statistical methods into robust, production-ready systems
  4. Work closely with Product, Design, and Engineering leadership to influence the direction of the product, on both a day-to-day and the big picture vision
  5. Educate engineers, leaders at Datadog, and our largest customers on statistical best practices, experiment design, and practical inference
